Title: Dyeing with vat and sulfur dyestuffs
Filed: 1951-07-09
Abstract: Textile material is impregnated with an aqueous composition comprising a vat or sulphur dyestuff and reducing agents therefor, passed into a bath of an inert water-immiscible oil maintained at a temperature above the boiling point of the water in the dyestuff composition so as to generate steam beneath the surface of the oil, removed from the oil before complete evaporation of the moisture contained therein, and then subjected to oxidation development of the dyeing.  The steam-in-oil emulsion adhering to the textile material on leaving the oil bath is preferably removed by pressure rolls, and the residual oil then removed by means of an aqueous solution of a dispersing agent. The moisture retained by the material after expressing the emulsion may be from 1 to 25 per cent of the weight of the p  material.  The textile material may be padded with the dyestuff in its reduced form, or it may be padded with the dyestuff pigment, dried, and then padded with an aqueous solution of the reducing agent.  The time of immersion in the oil bath may be from 1 to 30 seconds.  Suitable inert water-immiscible oils are saturated non-aromatic petroleum oils boiling from 120 DEG  to 400 DEG  C., silicone oils, and chlorinated or fluorinated higher boiling non-aromatic hydrocarbons.  Small amounts of an oil-soluble emulsifying agent such as mono-oleyl polyethylene glycol may be added.
